| 摘 要： | 目的:分析肱骨不同载荷加载下应力分布,探讨其相关的记忆生物力学意义。方法:选择湿肱骨标本行CT成像,大型有限元分析软件ANSYS5.6建立肱骨三维模型以及天鹅记忆加压接骨器(shapememoryconector,SMC)固定模型,同时进行相应力学分析。结果:当纵向加压的压力P=300N时,Z方向的正应力为-4.0～-4.5MPa,断面区域的压应力为0～0.2MPa。结论:SMC固定肱骨后三维有限元的分析,可以为肱骨骨折后内固定的力学研究提供新思路。

| Abstract: | AIM:To analysis the stress distribution of humerus by different direction loads and to find out its memory biomechanical significance.METHODS:CT scanned one wet humerus sample from corpse and the image of every layer of cross section of humerus were obtained. The humerus model fixated with shape memory connector (SMC) was constructed by means of Ansys5.6 software, and then corresponding mechanical analysis was performed.RESULTS:When the longitudinal load P=300N, positive stress in Z direction was - 4.0- - 4.5 MPa ,and in fracture cross section ,express stress was 0- 0.2 MPa. |

| Keywords: | The construction and three dimensional finite element analysis of humerus fixated with SMC provides a new method for continued research |
